Individuals with tetraplegia lack independent mobility, making them highly dependent on others to move from one place to another. Here, we describe how two macaques were able to use a wireless integrated system to control a robotic platform, over which they were sitting, to achieve independent mobility using the neuronal activity in their motor cortices. The activity of populations of single neurons was recorded using multiple electrode arrays implanted in the arm region of primary motor cortex, ...

Mobilization and deposition of iron nano and sub-micrometer particles (INSMP) in a porous medium were investigated using a water-saturated glass micromodel. The deposition and detachment of INSMP in the micromodel were visualized by taking serial images and experimentally verified by analysis of breakthrough curves. This first visualization study of INSMP fate showed that there were dense aggregations at the pores as the concentration of INSMP increased. The presence of dissolved humic substances (> ...

고압 인젝터의 성능은 디젤 연소엔진의 동력, 배출물, 연료소모와 직접적인 관계가 있다. 본 논문에서는 솔레노이드 코일과 피에조 세라믹으로 구동되는 커먼레일 디젤 분사용 인젝터의 응답 특성을 AMESim 코드를 사용하여 상대 비교 연구를 수행하였다. 따라서 연료압력, 분공경을 주요 해석변수로 설정하였다. 본 연구를 수행한 결과, 솔레노이드 구동 인젝터에 비해 피에조 구동 인젝터가 상대적으로 더 빠른 응답성과 더 높은 제어성을 가짐을 알 수 있었으며, 특히 다단분사 적용시, 이런 결과가 매우 효과적임을 확인할 수 있었다.
